Functions

Protection of an electrical installation

and all electrical and electronic devices

connected to this installation against

destructive surges. Such voltage surges

can be generated by lightning induced

currents, by network polluting devices

(such a motors, frequency converters,

dimmers, etc..) and by power supply

networks switching operations.

Standards

IEC 61643-I

IEC 61643-II

DIN VDE 0675-6

NF C61-740

BS 6651

Marking

SurgeGuard

Applications

Surge arresters cover the protection of home appliances (TV, Hiﬁ , VCR,

laundry machine, dishwasher...), commercial building equipment (computer,

data networks, intrusion and alarm systems, access control and building

automation systems), but also industrial equiment (PLC, instrumentation,

medical apparatus, monitoring devices) and even the protection of entire off-

shore drilling platforms.

Features

• The line of surge arresters includes a full range of compact protectors for

installation on DIN rail. The SPD's are especially designed to provide complete

and effective protection against surges, protecting equipment and property

connected to the low voltage network.

• The range includes Class I/B 15 kA to 100 kA surge arresters in 10/350 ms

wave form, and Class II/C surge arresters with different discharge capacities:

15 kA, 40 kA and 100 kA in wave form 8/20 ms. Class II SPD’s for DC photo-

voltaic applications, communication and TV lines are also available. The most

suitable value will be selected according to the type of installation, premises

and equipments to be protected.

• Several different formats one pole, single phase, two phase and three phases

are available for all types of electrical net systems: TT, TN-S, TN-C, IT.

• Additionally, dedicated versions for temporary overvoltage (TOV) are included

in the offer.

TOV is a voltage peak of hundreds of volts for an indeterminate period due

to the unbalance of the network (normally caused by neutral fault).
